Mutual certification between M2M terminating gateway and carrier network comprises the certification of equipment and the certification of user, M2M terminating gateway specifically for: be wherein provided with equipment vendor distribute key K v (also referred to as device keys Kv), the key K o (also referred to as user key Ko) that operator distributes, the two-way authentication between M2M terminating gateway and carrier network realizes based on permanent general character key K v and key K o.Wherein, key K v and key K o is all stored in the trusted context of M2M terminating gateway, and namely the external world cannot know, operator can obtain key K v by other trusted channels from equipment vendor.
Like this, together with M2M terminating gateway is bundled in SIM card, the stolen or clone's M2M gateway terminal of SIM card all can not cause illegal access.
When M2M terminating gateway does not exist, be also suitable for the direct certification of network with M2M terminal with upper type.
Mutual certification between M2M terminal and M2M terminating gateway comprises the certification of user class certification and device level.M2M terminal specifically for: wherein store the key K v ' that equipment vendor distributes, and the key K o ' that operator distributes, the two-way authentication of M2M terminal and M2M terminating gateway is based on the key K v ' shared and key K o '.Wherein, key K v ' and key K o ' is stored in the trusted context of M2M terminal, and operator can obtain key K v ' from equipment vendor, and key K v ' and key K o ' is downloaded to M2M terminating gateway by operator.
Described M2M terminal is the key K v ' of M2M terminal distribution from equipment vendor request equipment business specifically for the certificate server of: described carrier network; The key K o ' that described Kv ' and operator distribute by the certificate server of described carrier network, or f (Kv ', Ko '), send to M2M terminating gateway; Described f (Kv ', Ko ') be with the function of described Kv ' and described Ko ' as parameter; Described M2M terminating gateway and M2M terminal, according to described Kv ' and described Ko ' or f (Kv ', Ko '), realize the two-way authentication between M2M terminal and M2M terminating gateway.
As shown in Figure 1, M2M terminal (i.e. M2M terminal 1, the M2M terminal 2 in Fig. 1 of same M2M terminating gateway is connected to ... M2M terminal i) belong to same group.M2M terminal is changed group and is referred to, M2M terminal is connected to another M2M terminating gateway, and now, the key K v ' of M2M terminal and key K o ' can download in the M2M terminating gateway be newly connected by carrier network.
As shown in Figure 1, present system have employed layering authentication mechanism, first realizes the certification of carrier network to M2M terminating gateway, and certification comprises the certification to equipment and the certification to user, ensure that M2M terminating gateway is not distorted by malicious user, attacks or clone; Then, realize the certification of M2M terminating gateway to M2M terminal, certification equally also comprises the certification to equipment and the certification to user, by M2M terminal authentication system of the present invention, greatly reduce the signaling traffic load that carrier network increases greatly owing to supporting M2M business, thus ensure that the service quality that M2M serves, and then ensure that communication quality.
Below in conjunction with embodiment, the method that present system realizes certification is described in detail.
Fig. 2 is the schematic flow sheet of the embodiment of mutual certification between M2M terminating gateway of the present invention and carrier network, as shown in Figure 2, comprises the following steps:
Step 200: pre-set the key K v of equipment vendor's distribution and the key K o of operator's distribution in M2M terminating gateway.Here, key K v and key K o needs to be stored in the dependable environment of M2M terminating gateway.
Step 201: the certificate server of carrier network asks the key K v of M2M terminating gateway to equipment vendor.In this step, the certificate server of carrier network needs to provide the mark that uniquely can identify M2M terminating gateway to equipment manufacturers, the such as equipment Serial Number etc. of M2M terminating gateway.
Step 202: equipment manufacturers return the key K v of the M2M terminating gateway of request to the certificate server of carrier network.In this step, communication between equipment manufacturers and the certificate server of carrier network needs mutual certification, and the transmission of the information between them is through the i.e. safety of encryption, specific implementation can adopt existing a lot of method, belong to the conventional techniques means of those skilled in the art, repeat no more here.
Step 203:M2M terminating gateway sends access request to carrier network, the user ID of M2M terminating gateway is carried in access request, such as international mobile subscriber identity (IMSI, InternationalMobileSubscriberIdentity) etc.
Step 204: carrier network forwards access request to certificate server.
Step 205: certificate server, according to the user ID of M2M terminating gateway, finds key K v and the key K o of this M2M terminating gateway, and generates Ciphering Key according to them.The specific implementation of this step can adopt existing mode to realize, as the authentication mode-AKA of existing 3GPP network, and emerging mode etc., the protection range be not intended to limit the present invention here.
Step 206: AKA Ciphering Key (RAND ‖ XRES ‖ CK ‖ IK ‖ AUTN) is transmitted to carrier network by certificate server.
Step 207: the key that carrier network and M2M terminating gateway distribute according to equipment vendor and equipment identities (key that operator distributes) carry out key agreement mechanisms (AKA, AuthenticationandKeyAgreement) certification.
By the flow process shown in Fig. 2, M2M terminating gateway and carrier network establish trusting relationship, and M2M terminating gateway and carrier network can be set up encrypted tunnel by this trusting relationship and protect signaling and media data.
Fig. 3 is the schematic flow sheet of the embodiment of mutual certification between M2M terminal of the present invention and M2M terminating gateway, as shown in Figure 3, comprises the following steps:
Step 300: pre-set the key K v ' of equipment vendor's distribution and the key K o ' of operator's distribution in M2M terminal, here, key K v ' and key K o ' is stored in the dependable environment of M2M terminal.
Step 301: the certificate server of carrier network asks the key K v ' of M2M terminal to equipment manufacturers.In this step, the certificate server of carrier network needs to provide the mark that uniquely can identify M2M terminal to equipment manufacturers, the such as equipment Serial Number etc. of M2M terminal.
Step 302: equipment manufacturers provide the key K v ' of the M2M terminal of request to the certificate server of carrier network.In this step, the communication between equipment manufacturers and the certificate server of carrier network needs mutual certification, and the transmission of information between them is through the i.e. safety of encryption.
Step 303: the key K o ' that the key K v ' of M2M terminal and operator distribute by the certificate server of carrier network, or f (Kv ', Ko ') send to carrier network.
In this step, and f (Kv ', Ko ') be a kind of function, this function with key K v ' and key K o ' as parameter, derive a sub-key, complete mutual certification using this sub-key as shared key, effect is equal to using key K v ' and key K o ' as shared key.Here need M2M terminal also to do the same operation, derive an identical sub-key.
Step 304: carrier network is by the key K v ' of M2M terminal and operator key Ko ', or f (Kv ', Ko ') sends to M2M terminating gateway.
Step 305:M2M terminating gateway and M2M terminal use shared key i.e. (key that equipment vendor distributes) Kv ' and (key that equipment vendor distributes) Ko ', or f (Kv ', Ko '), realize the two-way authentication between M2M terminal and M2M terminating gateway.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention, and all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
